RMGM Promotions

What RMGM Promotions does

RMGM Promotions is a privately held, Denver, Colorado-based event production company that organizes and promotes mineral, fossil, gem, and meteorite shows across three U.S. states. The company's core product is a recurring annual calendar of in-person shows — the Colorado Mineral and Fossil Shows (Spring at National Western Complex in Denver; Fall at Delta Hotels Denver in Northglenn), the Texas Mineral and Fossil Shows (Dallas/Plano and Conroe), and the RMGM Tucson Mineral and Fossil Tent Show — each featuring retail and wholesale dealers from around the world. Attendee admission and parking are free; the company's primary revenue stream is vendor booth fees, with a secondary revenue stream generated through its online marketplace, RockyGems.com, which enables dealers to reach collectors between in-person events.

The business was originally founded as Rocky Mountain Gems and Minerals by Sandra Gonzales, who purchased the shows from longtime promoter Martin Zinn in 2015 and rebranded the company as RMGM Promotions. Under her ownership, the company has expanded geographically from a single Colorado operation to a multi-state footprint spanning Colorado, Texas, and Arizona, and has extended its digital surface area with the launch of RockyGems.com, which offers searchable dealer listings, expert articles, and instructional jewelry/wire-wrapping videos alongside the marketplace. The underlying technology stack is lightweight: an event management and show organization platform supporting vendor registration, show calendars, and the e-commerce marketplace, with no proprietary tech assets, AI capabilities, or external integrations documented. Marketing is conducted through organic social media, an email newsletter, website content (vendor spotlights and articles), and event marketing.

RMGM serves a two-sided market: (1) international mineral, fossil, gemstone, meteorite, and jewelry dealers who rent booth space to access a concentrated collector audience, and (2) collectors and hobbyists ranging from casual enthusiasts to serious buyers who attend shows free of charge. The company's value proposition centers on curation of "trusted and reputable dealers" with on-site Show Identification, family-friendly accessible venues with free admission and parking, and year-round collector engagement through the RockyGems.com marketplace. The company is founder-owned and operated, with no disclosed institutional investment, parent company, or external funding.
